% I - logical array representing removed points
% pvPairs - pv-pair cell array which can be passed to "set" on the
% graphic object to display the results of the remove operation.

% The results of this method may need to be augmented for graphic
% objects such as scatter where additional properties such as
% SizeData and CData are effected by removing brushed data.
